My question is very simple but I don't know the way...

I'm beginner so please help me.

I use "syms" and make a function.

and then, after some process, the funcction's expression is like below.

(7248263982714163 * x)/2251799813685248 - 3086369634568075/2199023255552

It is a linear function (ax + b) -> 'a' is slope and 'b' is y-intercept .

And, I want to get the function automatically like below.

3.2189*x - 1403.5

(because it is better to understand)

Please help me..
